Comparative Analyses of Primary and Secondary Amines for CO<sub>2</sub> Chemical Process Capture in a CFBC Pilot Installation

Cristian Dinca, Member
Abstract—The aim of this paper is to optimize the integration of post-combustion CO2 capture by chemical absorption in the technology of circulating fluidized bed combustion of coal, by comparing the effects of the usage of primary amines (MEA) and of secondary amines (DEA). The validation of the results obtained after the HYSYS 3.2 modeling of the CFBC technology with post-combustion CO2 capture by chemical absorption was based on experimental results. The minimum quantity of required energy (2.65 GJ/tCO2) was obtained in the case when DEA (40 wt.%) was used, for the following values of process parameters: the CO2 capture process efficiency of 85%; the ratio L/G = 1, lean loading solvent was of 0.22 mol_CO2/mol_DEA, the rich solvent loading was of 0.45 mol_CO2/mol_DEA; the stripper inlet solvent temperature was of approximately 85 oC, while the optimal number of stages in the absorber was 8.

Index Terms—CO2 capture, CFBC, MEA, DEA.
